Abstract

The invention discloses a bacillus cereus and probiotics powder thereof as well as preparation and application of the probiotics powder. Bacillus cereus BC158 is separated, purified and screened from excrement of healthy piglets and has a collection number of CGMCC (China General Microbiological Culture Collection Center) No.7433. The bacillus cereus has high acid resistance, high cholate resistance, high adhesive force and high safety, has a certain inhibitory property to common pathogenic entero becteria and can produce amylase, protease and cellulase. According to preparation of the probiotics powder of the bacillus cereus, a step-to-step magnified four-stage culture process is adopted, high-density culture of the bacillus cereus BC158 is realized through a ventilated and mixed submerged liquid fermentation technology, and high-temperature protection effects of corn starch and other auxiliary materials are combined to realize high-density recovery of bacillus cereus in the fermentation liquor. The preparation method is simple and low in cost, the spore rate in the prepared probiotics powder is over 95 percent, the content of viable bacteria in the bacillus cereus is 3*10<9>-5*10<10>CFU / g, and the bacillus cereus can be applied to feed additives in animal breeding.

Description

technical field

[0001] The invention relates to the technical field of microbes, in particular to Bacillus cereus BC158 and its probiotic powder, as well as the preparation and application of the bacteria powder.

[0002] Background technique

[0003] The food safety project from the farm to the dining table is a very complex project. As a part of the food chain, feed safety is undoubtedly an important link. Therefore, it has broad prospects for strengthening the research and development and application of safe feed additives. Modern intensive animal husbandry restricts animals from contacting the soil and the surrounding natural environment. This feeding condition is not conducive to the establishment of normal flora in the gastrointestinal tract of animals. When the external environmental conditions change, it is easy to cause the imbalance of micro-ecological flora in the gastrointestinal tract of animals and reduce the resistance to pathogenic bacteria. At present, this...
